The graph displays the percentage of students who are proficient and who are not proficient on the Illinois Science Assessment.

This is a zero-based graph. The percentage of students who are not proficient is shown to the left of the zero line. The percentage of students who are proficient is shown to the right of the zero line.

The display can be customized for more detailed information. Select Grades & Demographics on the horizontal menu near the top of the display. To view this information, click on any of the drop down menus in the gray area. Click the box next to your selections. Then click the blue Add button.

Mouse over any square in the color key and that performance level will be highlighted.

Note: If a student group has fewer than 10 students, no information is displayed.

The Illinois Science tests are designed to measure performance against rigorous science standards. The tests require students to apply their science skills to answering questions. These skills are necessary in order for students to be successful in the real world. The science tests are given to students enrolled in grades 5 and 8. At the high school level, the assessment is course-based and corresponds to the content of Biology I. The tests last about an hour, and students take them online.

Based on test scores, students are determined to be proficient or not proficient in science. Proficient is defined as work that meets the standard. It is acceptable work that demonstrates application of essential knowledge and skills. Minor errors or omissions do not detract from the overall quality. Not Proficient is identified as work that does not meet the standard. It shows partial but inconsistent application of knowledge and skills.The Illinois Science Assessment results will also be used to measure student growth for school and district accountability.
